Abstract
Description
本实用新型属于轨道板领域，尤其是涉及一种单根同组自动张拉锁紧装置。The utility model belongs to the field of track plates, in particular to a single root automatic tensioning and locking device.
预应力混凝土是为了弥补混凝土过早出现裂缝的现象，在构件使用(加载)以前，预先给混凝土一个预压力，即在混凝土的受拉区内，用人工加力的方法，将钢筋进行张拉，利用钢筋的回缩力，使混凝土受拉区预先受压力。这种储存下来的预加压力，当构件承受由外荷载产生拉力时，首先抵消受拉区混凝土中的预压力，然后随荷载增加，才使混凝土受拉，这就限制了混凝土的伸长，延缓或不使裂缝出现。在进行张拉时，当张拉杆的张拉达到设计力值后，需要将张拉杆上的锁定螺母锁紧，使钢筋一直保持受力状态。现有的技术，对于所有张拉杆是经过同一个千斤顶进行统一的张拉，难免会导致张拉杆的受力不均，影响最后的产品质量。并且都是通过人力进行一个接一个的螺母锁紧操作，费时费力，影响效率。Prestressed concrete is used to compensate for the premature cracking of the concrete. Before the component is used (loaded), the concrete is pre-stressed in advance, that is, in the tension zone of the concrete, the reinforcing bar is tensioned by manual force. The retractive force of the steel bar is used to pre-stress the concrete tension zone. The stored pre-stressing force first compensates for the pre-stress in the concrete in the tension zone when the component is subjected to the tensile force generated by the external load, and then the concrete is pulled as the load increases, which limits the elongation of the concrete. Delay or not cause cracks to appear. When the tension is pulled, when the tension of the tension rod reaches the design force value, the lock nut on the tension rod needs to be locked, so that the steel bar is always stressed. The existing technology, for all the tension rods to be uniformly tensioned by the same jack, will inevitably lead to uneven tension of the tension rod, affecting the final product quality. And the nut lock operation is carried out one by one by manpower, which is time consuming and laborious, affecting efficiency.
